This research advances Wireless Sensor Network (WSN) theories in support of the exploration and mapping of Mars. A Mars Tumbleweed Rover is designed to use wind to propel a network of sensors across the Martian surface. While navigating the surface of Mars, the rovers' collect, aggregate, and communicate environmental and spatial sensor data. The Mars Tumbleweed program envisions releasing numerous...
In this paper, we address the issue of handling uncertainty and information fusion for an efficient WSN deployment. We present a flexible framework for collaborative target detection within the transferable belief model. Using the developed framework, we propose an uncertainty-aware deployment algorithm that is able to determine the minimum number of sensors and their locations such that full area...
This paper presents a probabilistic transmission control technique for the distributed estimation in WSNs. The presented technique is based on a novel transmission control which is to minimize a mean squared error of estimation by increasing the packet transmission success probability of only sensors having the high observation SNR. In the presented method, the transmission of sensors is probabilistically...
Unattended Wireless Sensor Networks (UWSNs) operated in hostile environments face a risk on data security due to the absence of real-time communication between sensors and sinks, which imposes sensors to accumulate data till the next visit of a mobile sink to off-load the data. Thus, how to ensure forward secrecy, backward secrecy and reliability of the accumulated data is a great challenge. For example,...
This study investigates the graph theoretic implications of applying collaborative rate-adaptive storage and data management to enhance the reliability of connectivity-challenged sensor networks employing dynamic heterogeneity setups. The topologies of sensor networks are synthesized through a spatially-dependent probabilistic random graph model. Around this model a degree-density-connectivity-clustering...
Wireless sensor networks (WSN) have recently achieved a great deal of attention due to its numerous attractive applications in many different fields. The focus of monitoring application is to acquire and verify information about enemy capabilities and positions of hostile targets. Monitoring applications related to security and reliability requires guaranteed k-coverage of the area at all times. A...
